1. 环境

nagios分为客户端与服务端

服务端(监控机)放在中控机上

客户端放在各个服务器上

服务端环境: centos7 10.0.0.111

客户端环境: Ubuntu16 10.0.0.141

2.服务端的安装

忘记了, 很久以前装的服务端

3. 客户端安装

安装plugins

apt install gcc openssl libssl-dev

wget https://nagios-plugins.org/download/nagios-plugins-2.2.1.tar.gz

cd nagios-plugins-2.2.1/

./configure --prefix=/usr/local/nagios

make && make install

chown -R nagios.nagios /usr/local/nagios

安装nrpe

wget https://github.com/NagiosEnterprises/nrpe/releases/download/nrpe-3.2.1/nrpe-3.2.1.tar.gz

tar zxvf nrpe-3.2.1.tar.gz

cd nrpe-3.2.1

./configure

make all

make install

make install-plugin

make install-daemon

make install-config

make install-inetd

make install-init

vim /usr/local/nagios/etc/nrpe.cfg
allowed_hosts=127.0.0.1,::1,10.0.0.111

service start nrpe
service enable nrpe

/usr/local/nagios/libexec/check_nrpe -H 127.0.0.1    # NRPE v3.2.1

在服务端再测试一下

/usr/local/nagios/libexec/check_nrpe -H 10.0.0.141 # NRPE v3.2.1
